VENTILATING Doon.

'Application'filed February 21, 1927. SerialNo. 169,962.

My invention relates to improvements in Ventilating doors.

tion, which may be used as an ordinary door,

or which may be arranged to serve the purposes of a louver door, which will afford `good ventilation in a room, and will permit of the elimination of transoms while aifording their functions, and which, when used as an ordinary door, will present atone side j the appearance of a single panel door and at its opposite side the appearance of an or-` dinary two panel door.

A further objectofmy invention is to provide a novel door` of the kind described, which is simple, cheap to malle, durable, not liable to `get outof order, which is easy to operate, and which may be hung and operated like an ordinarydoor.

The novel features of my invention are hereinafter fully described and cl aimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Fig. 1 is a perspective view of my improved door, the panel and the wings being shown in the open position.

Fig. 2 `is an elevation of the same showing the wing side of the door.

Fig.`3 is an elevation showing the other side of the door.

Fig. 4 is an enlarged section on the line 4-4of Fig.,2.

Fig. 5 is a vertical section of the door with the parts disposed as shown in Fig. 1.

Fig. 6 is an enlarged section on the line 6-*6 of Fig. 5.

Fig. 7 is an enlarged section on the line 7--7 of Fig. 2.

Similar reference characters designate similar parts in the diiferent views.

The body of the door comprises the usual stiles 1, top rail 2 and bottom rail 3. The body is provided wth an opening extending between the stiles 2 and the rails, the opening being designated by 4.

Fastened to the. inner edges respectively of the stiles 1 and the rails 2 and 3 are fillets 5, which serve as stops for limiting the movement of a panel 6, past a parallel position with the body, in one direction. The panel 6 in said parallel position, Fig. 3, closing said opening 4, whereby the door at the side of the panel next to the stop fillets simulates the appearance of an ordinary one panel door, when the panel is in position.

The panel 6 is hinged at its lower end to the upper edge of the bottom rail 3, so as to swing on a horizontal axis from the closed position, shown in Fig. 3, to an inclined open position, shown in Figs. 1 and 5.

Two imperforate wings, preferably rectangular and designated by 7, are respectiven ly hinged at one set of their longitudinal edges to the stiles 1, so as to be swung from a position parallel with the body of the door, in which they overlap the panel 6, when the panel is closed, Fig. 2, to positions at right angles to the body, as shown in Figs. 1 and the closed parallel -I'n the angular positions, whenthepanel f 6 is inclined, the adjacentsides of the wings 7 will be respectively adjacent to the longitudinal edges of the panel 6.

The wings 7 may be provided with spring hinges S, the springs oitwliieh normally automatically force the `wings tothe positons parallelV with the body of the door and against the adjacent side of the panel 6, the latter being in the closed position, Fig. 2. The door at the wing side thereof,with the panel and wings closed, presents the appearance of an ordinary two panelfdoor, the adjacent longitudinal edges of the wings 7 being spaced from each other, as shown.

For releasably locking the panel 6 Yin the closed position, by any suitable means, asby y a vertically slidable bolt 9 mounted Vin a casing 10 fastened to the panel 6, the bolt being normally forced by a coil spring 11 in the casing 10 to a position in which the bolt is adapted to enter a strike plate 12 fastened to the under side of the top rail 2, Figs. 1, 2 and 7.

For limiting the opening movement of the panel 6, suitable means may be employed. For this purpose, I have shown, Figs. l, 5 and 6, two holding members 13 respectively fastened to the sides of the wings 7 next adjacent to the panel 6, each member 13 having in it a longitudinal slot 14 which extends` from the end of the member, next adjacent to the hinged edge of the wing, to a point spaced from the other end of the member. The wings 7 are provided respectively with grooves 15 respectively co-extensive and registering with the slots 14.

Respectively mounted on opposite longitudinal edges of the panel 6 are two plates 16 each having a laterally extending T shaped projection 17. The projections 17 are respectively adapted-to enter the slots 14 and grooves 15 and to travel therein until the projections 17 strike the closed ends of the slots 14, whereby the panel 6 is limited in its opening movement to the inclined position shown in Figs. l and 5. The outer extremities ot the projections 17 are respectively adapted to slidably engage the inner sides of the members 13, whereby, when the wings are in the angular positions and the panel is in the inclined position, the wings 7 will be held from movement away from the panel G.

In the operation ot the invention, to open the panel'and wings, the bolt 9 is drawn downwardly out of engagement with the strike plate 1Q, as by a chain 18, which may depend from the bolt. Iy pulling on the chain 18, the panel is swung from the closed position, Fig. 2,' to the inclined position, shown in Figs. 1 and 5, and in so moving, the panel G swings the wings to the angular positions, the projections 17 eil'ecting engagement, during such movement ol the panel and wings, with the members 13, whereby the opening moven'ient of the panel is limited, and the wings are held closely adjacent to the panel, as before described. An opening will thus be provided between and at the upper ends of the panel and wings, whereby air may pass through the opening 4 into the room or out ol the room.

The door will thus serve the purpose of a transom or that of a louver door, without anyT one at the exterior of the room, due to the impert'orate wings closing the spaces at the side edges of the panel 6, being'able to make observations of the room, excepting of a portion of the ceiling.

To close the panel, it may be swung to the vertical position, upon which the bolt 9 will engage the strike plate 12, thus locking the panel closed, and the springs of the hinges 8 will automatically swing the wings 7 .so that they willov erlap the panel G, as shown in Fig. 2.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claim, may be made without departing from the spirit of my invention.

What I claim isz- In a Ventilating door, a door having a body provided therethrough with a ventilating opening, two wings hinged to said body at opposite sides respectively olsaid openings so as to swing from positions parallel with to positions at right angles to said body, each wing on its inner side having a transverse groove extending from its hinged edge, two plates respectively fastened to the inner sides of said wings, and respectively extending over said grooves, each ot said plates having therethrough a longitudinal 'slot registering with said groove which is covered by said plate, a panel hinged to said body between said wings so as to be swung from a position closing said opening to an open inclined position, kand two members fastened to said panel at the ends respectively thereof, each of said members having a T shaped projection extending through and adapted for travel in the adjacent one of said slots and having its head in and adapted for travel in the adjacent groove and in slidable engagement with the inner side of the adjacent one of said plates, whereby the wings move conjointly with the panel from positions at right angles to the panel, when the latter is opened, to positions overlapping the panel, when the latter is closed.

In testimony whereof I have signed my name to this specification.
